Application filed July 29, 1912. Serial No. 712,136.

` To all whom t may concern Be it known that I, BENJAMIN F. Ariens TINE, a citizen of the United States, residf ing at Buffalo7 in the county ofErie and State of New York, have invented certain new and useful Improvements in Rotary ExplosionfEngines, of which the following is a specification.

This invention relates to explosion engines and more particularly toengines of the rotary type.

One object resides in the provision of an explosion engine embodying a casing provided with an explosion chamber inA Which is rotatably'niounted a piston carrier pro vided with pistons in combination with a means larranged within the casing of the engine for forming and compressing an ex-v plosive fluid with a valved passage between the fluid forming and compressing means 4andthe explosion chamber so as to regulate the supply of fluid to the forming and compressing means and of the compressed fluid from the forming and compressing means to the explosion chamber.

Another object is to provide a rotary eX plosion engine having a rotatable piston carrier and a fluid forming and compressing means which is operable under the influence of the rotatable piston carrier and which is arranged within the explosion chamber so thatthe heat units of the latter are utilized to bring the fluid to a proper degree of' efficiency to effect a perfect coni- 'bus'tible explosive fluid with a valve to pio' vide for a charging of the forming and compressing means and to effect a transfer of the compressed fluid from the forming and compressing means to the explosion chamber of the engine where it is exploded to drive the rotatable member.

Anotheriabjeet is to provide a rotary explosion engine including a casing having an explosion chamber and a rotatable piston carrier mounted therein with an intern/al fluid. forming and.coinpressing means be- 'tween which and. the explosion-chamber and confined within the rotatable piston carrier there is disposed means to simultaneously control the supply of fluid to the forming and compressing means and also 'to effect a transfer of the compressed fluid from the forming and cmnpressing means to the explosion chamber where it exploded to drive the rotatable member.

Another object is to provide a rotary exI4 plosion engine embodying a casing having an explosion chamber in which is mounted a rotatable member provided with pistons adapted to slide radially thereof and also provided with fluid forming and compress` ing chambers in Which are mounted reciproeating plungers, means for connecting the pistons so that one will counterbalance the other with means connecting the plungers so that one plunger will counterbalance the other and with the connectin means beltween the plungers and the pistons operatively connected together.

Another object resides in the provision of a rotary explosion engine having an explosion chamber` therein .in which is mountedv a rotatable piston carrier in which latter isvlocated means for forming and compressing the fluid for explosion in the' explosion chamber todrive the rotatable member, the forming and compressing means including plungers confined Within .the rotatable member and thereby shielded fromrthe direct heat and explosion of the gases in the explosion chamber of engine.

Another object is to provide a rotary eX- plosion engine having an explosion cham' ber in which is mounted a rotatable piston carrier and a fluid forming and compressing means which is operable under' the influence of theA rotatable piston carrier and which has communication With the explosion chamberof the engine through suit-v able .controlling means adapted to govern the supply of the fluid to the forming and compressing means and also to control the supply of the compressed fluid from the forming and compressing means tothe explosion chamber.

A' still further object is to provide a ro-V tary explosion engine including a casing having \an explosion chamber therein in which is mounted a rotatable piston carrier means consisting preferably pt oppositely, disposed. fluid compressing chambers ipa each of which are plungers suitably con# nected together to reciprocate them in the compressing chambers with means arranged to effect a charging -of one compressing chamber under the' suction stroke of its plunger and simultaneously transfer the fluid under the compression 'stroke of the and also a fluid forming and compressing '100 to the explosion chamber Where it is eX- ploded to drive the rotatable member.

It is still further designed to provide a rotary explosion engine having an explosion chamber and a rotatable piston carrier mounted therein with fluid forming and compressing means confined Within the explosion chamber and including' plungers connected together so that one plunger counter# balances the other.

lilith the above and other objects the present invention consists in the combination and arrangement of parts hereinafter more fully described, illustrated iii the accompanying drawings and particularly pointed out in the appended claims, it being understood that changes may be made. in the form, proportion, size and ininoi-cletails without departing from the spirit or sacrilicing any of the advantages of the inve-n` tion. j

F ig. 1&1 is a fragmentary View of the piston carrier illustrating' one of the frictionI reducing members carried at the ends or' the pistons. Fig. 15 is a detailed 4perspective vievv of one of the friction reducing members carried by the pistons.

Referring now more particularly to the accompanying drawings the casing or frame of my improved engine consists of a suitable supporting base 10 on which is mounted a cylinder 11 against the inner :tace 12 ot which is disposed the abutment 13.

At each end of the cylinder are suitable end plates 14. These plates are preferably bolted to the end walls of the cylinder and are provided with Ycentral openings in which are located'bearings 15 in, which rotates the main drive shaft 16 which latter menace throughout a portion purpose presently exis 'preferably hollow oiz its length for a piained.

Suitable packing and glands may be used for the main shaft. Said end plates on their inner faces are cut away so as .to form. a recess in which are located operating mechanisms for thc radial pistons of the piston carrier and the plungers of the compressing mechanism, which Will be herein after more fully described.

The abutmentl is formed with a cylindrical chamber 17 Which is eccentrically disposed in the abutment so that saidabutment is in effect cam shaped in cross section. In this chamber 17 is disposed a piston carrier 18 which is so proportioned as to engage the Wall of the cylindrical chainber 17 at the point 19. The radial pistons are indicated at 202and 2l and are so proportioned as to be held continually in contact with the Wall. of the cylindrical chamber 17 as the piston carrier rotates.

The abutment is formed on its outer face with a centrally disposed circumferential rib 22 which fits snugly within the cylinder 12 so that any lateral thrust against the abutment will be imparted through said rib to the supporting cylinder of' the en gine. This rib 21. forms at each endkof receive the caps 23. These caps 23 are carried by the rotatable piston carrier by means of suitable fastenings 2l, if not` cast therewith. I

The outer tace of the abutment on` opposite sides of said ribs is still furthercutaway so as `to form. a series of chambers which are circumferentially arranged about the abutment and extend froml aY point adjacent the center rib 21 to the ends of, the abutment. TheseV chambers are separated by ribs 26 extending longitudinally ot lthe abutment. Each cap 23 has a shoulder 23 adapted to close the outer ends of the chambers 25 and the caps arejso proportioned as to have a smooth running fit` with the ribs 26. Each chamber 25 is connected with .the cylindricalchamber 17 `by a port 27. The combined area of the chambers 25` in the outer surface'of the abutment is sub stantially the same as thearea of the outer surface of the rotating piston carrier. As the piston carrier rotates the radial piston Will uncover one port 27 after another so that the surface on the rotating carrierexposed to pressure is kept substantially equal to the 'surface on. the caps 23 covering the chambers 25 which are exposed to the sameforces of pressure. The result is thatinaemuch as these pressure forces are opposed to each otheir, the one will counterbalance the other and therefore all the. objectionable lateral strains on the pistori carrier areneuthe abutment cutaway portions adapted to 45 '-"way 36 in whichroller or other bearings5- 37 are guided and `which are ada ted to 'tralized so that the carrier ivill `rotate freely 4on its bearings .regardless .of the pressure loads in the expansion or explosion chainber 17.- B" virtue of this counterbalancing y action the' carrier runs smoothly VWithout vibrationor chatter even though the carrier i be off center. -4

lThe'piston carrier 18 is rigidly connected with the main shaft 1G, as above stated, andis so proportioned as to ha-ve a smooth run,A

ning contact with the Wall of the cylindrical chamber 17 in the abutment 13. This Wall of the abutment at 'the pointof Contact between the carrier and the abutment may be' provided Vwith a plurality of slots 29 through which lubricant may be inserted so as to fill the chambers with -the-'lubricant to provide for a smoothrunningjoint the cylindrical chamber in the abutment and the abutment. These slots are covered by the rotatable carrier because ofthe run connection between the aforesaid caps and ning fit-of the Vcarrier with the-abutment at this point. The piston carrier i-s'forined with oppo-v sitely disposed radial grooves in which are mounted the'radial pistons 20 and 21.

vEach end of the piston carrier 18 is provided withl a flange or annular plate 31. The inner faces of these plates 3 1 form walls which together Wi'ththe outer `surface-ofthe piston and the inner surface of,

a portionof 'the abutment intermediate its ends form the' 4explosion chamber 1 7 of the engine. i These end'plates`31 are formedl with Vradial grooves 32ivhi6h are similar to tberadial grooves 30 in the piston carrier.

The radiali'pistonsextend into the' radial grooves orvguideways 32-in the end plates Mounted. on each' end of each radial piston-is a plate 33 each provided with a slot 34 which -embraces the ip iston and With lugs 35 adapted'to lengage the inner and outer edges of the pistons. On each side edge ofv each plate 331s a grooved 'guidebear `and roll- 'against the shoul ers 38 formed by milling theouter sides ofthe' plates 31 adjacent the guide- Ways 30. These plates 33 with their rollers are so disposed to' take upside thrust against the radial pistons and to provide for a free easy movement of the pistons 20 and 21 in their radial movement, relative 'to the piston carrier. The end plates 31 may bemadesolid or they may 'bei vcut away centrally1 thereof' to lighten the saineV the essentialfeatu-res vbeing the outer smooth circumferential surface .which fits snugly within the balancing capsI 23 and Wallsof the explosion chamber. ne of caps vided, if desired, witliheaded'pins 41 which.

The outer edges ofthe radial pistons may be provided with longitudinal grooves in which may be mounted packing strips which areyieldingly foi-.ced outwardagainst theA wall ot' the abutment by Isprings 56.

' These packing strips 55 are relativelylight.

and the lcentrifugalforce acting thereon will merely hold the same in smooth running Contact with thewall of the chamber' 17.

By the'A above construction it will be' ap- 'parent that l have provided a piston carrier with radialv pistons which are so operated as to be held insmooth ruiming contact -with the, wall 'of the explosion chamber, and regardless of lthespe'ed of the engine, saidv i radial pistons willbe properly counterbalzio als

anced one 4by the other so that all frictionand undue wear betweenthe radial pistons and thewall ofthe cylinder are avoided.

In the lrota-table piston carrier 1S there is formed oppositely disposed compression' chambers 57 and 58 which chambers extend 557-58 is a plunger 59' which extends throughout the length of thel corresponding vchamber and each of which has metallic or other packing strips 60=in its opposite. side faces Awhich engage the sides of the chamber.

These plungers 59 areadapted to move inward-ly and outwardly altei'nately'dui'ing ,"rotation of the piston carrier 18 land they .tween them andthe lrings 45.

are counterbalanced one by the other as are the pistonsQO-l. One way tocounterbalance the plungers v59 is to provide thev outer face of each with a Tfshaped` slot 61 which.

is open ended `and into each otivliichslotsjtl is loosely; positioned a-T-bar 62. These T`` bars 62 extend throughy slots 63 in the caps 23 with their extremities fitted in bearings' ,4H in lugs 63 and GJcrespectively, of com pensating rings 65 and 6 6 which latter are` from the 'sanne center` that is on the hubs 47 otl the end plates 14, with the compensating rings of the plunger-s having oscillatory movement with relation to each other at leach end of the engine as have the (-.oinpen-A sitting ringsA of the pistons at each .end of chamber fromthe 'lated to the extent that there isla lproporthe engine, the plungersand the pistons are .connected together.

. r lhc/,fluids tor. compression and subse- Aquent-transfer into'the explosion chamber for explosion to drive the rotatablemember vare mixed proportionably automatically in a mixing device consisting of a casing 68 which is preferably bolted `to the arui 69 secured by-ineans of bolts -70 or, otherwise .tofone of the end plates 1t ofthe gasolene chamber 72 and an airrchamber 73 and has aseries of ports 7J: which ,f gradually .increase in size. and which establish.communication.

between the gasolene and the air chambers'.

The casing 68 ot' the mixing device is provided with an opening which forms a valve` seat on which is normally seated a valve 75, there being a spring 76 arranged between the. shoulders 77 on. the casing '68 anda collar 7S. on the stem 7 9' of theafalv'e 75 .to

.hold the latter normally seated.l The stem '79 of said valveextends through the outer` end ofthe casing 68. Apiston lvalve 8O is.;

slidably mounted through the outerend of Ythe casing 68 and has a series fof ports 80.

thereinwhich graduallyincrease. in size.- The piston .vali'e 80 and. the stem 79 are a link 81 with'the result vthat, when the valve 7 5 isA unseated .against the tension of the .preferably ladjustably connected together-'by l spi-'ing 7 6 in a manner to be hereinafter exf -plained, the .piston valve 80'is moved iiiwardly accordingly sogthat `the amountf` of gasolene permitted to pass into-'the airgasolene chamber is, regutionatc lamount of gasolene supplied to the air chamber for mixture with' the air. The` quantity offair entering the air chamber of thev mixing devicevis controlledpreferably by afbutterlly valve 82 and the gasoleneA o the gasolene` chamber 80 byis supplied t means of la i-pe vor the .like 83.

, To provi e for the control lof-itlie mixed Huid from the mixing device vto the com-- pression chambers and subsequent compresf sion of ltheiiuidan-d transfer thereof` vinto the explosion chamber,- I provide afsingle valve ywhich may be constructed by providing the hollow .portion of thelmain drive shaft 16 with upper and lower ports 87 and 88 which are adapted to rotate into and out of registration .with the `recess 85 inthe valvev memberi.' 'The hollow portion of the malin d/iv'e shaft 16 has other `upper, and lower ports S9 and 90 which are ada t'Y ed to hr1/rotated into land out of' registration with the port S16 in the valve member Si as the shaft .and rotatable carrierfldrotate so as to provide for the supply of the uid to the compression chnmbers.- For instance7 referring. to Fig. 4 and assuming that the rotatable memhe'r 18 is in rotation` the plunger 59 in the compressionl chamber 5S is compressing huid, and forcing it through the port 88 and into the recess 85 andthe l Lduct. 91 which is at this time in communication With the recess 85 and when, as shown in Fig. 2, the port 88 has passed beyond the recess -85 the duct 91 and port 88 are no ,Eloi-iger in communication with therecess 85. E lh'e fluid has been compressed and has been forced .into the explosion chamber 17 in the yj'me'ans'of an ordinary spark plug 92 conected up in any suitable manner with any suitable source of electric energy as will be explained more in detail hereinafter. The

"i explosion ofthefcharge ,of compressed fluid expanding and impinging against the pis- *ton 21 furnishes the force or impulse to rotate the rotatable member. The products of'combustion pass out of the explosion chamber 17 through the exhaust chamber o'whe'nthe' pistons pass the exhaust chamber 93 and .exhaust port 94. .Vhen the port 88 vpasses the recess the port 90 in the shaft 16 `registers with the port 86 in the fixed valve member 8l so that as the plungerin '..5 the compression chamber 58 moves out- Wardly there is created a vacuum or suc- .-,ti on which draws in an additional charge lofsfluids from the mixing device by way of l ftheY hollow valve member 84 and ports 90 liggend-'86 yinto the chamber 58. By the time the compression chamber 58 has reached theposition occppied in Fig. 2by `the chamber 57, its plunger 59 has reached its-outermost movement and the port of 35 vthe main drive shaft has passed the port 86. in the valve member 84 thereby cutting fgofl' supply to the compression chamber 57. "ljThe continued rotation of the rotatable "member 18 brings the ports 87-87 and 40 duct 95 into registration with the'recess 85 Vas were the ports 88e-88 .and the duct 91 Fig. 4 and by the time the duct 95 crosses entirely over the recess' .85 a compressed charge has been supplied to the explosion .45, chamber 17 by Way of said duct 95 for the explosion. The ports 87 and 88 are always in registration with the ducts 91 and 95 respectively because of the rotatable member n being fixed to the main drive shaft. l thus 5 0 supply a plurality of compressed charges to the explosion chamber on each rotation lof the rotatablemember, alternately form-- ing charges and supplying the formed charges to the explosion chamber, all

55 through a single valve having one lixed and one movable port.

When it is'desired to start the engine a .certain amount of compressed gases may be f led directly tov the combustion orl explosion :30 -chamber '17 thlfough a hollow supply port .-96l or a certain amount of explosive fluid may be supplied to the combustion or eX- plo'sion chamber 17 and compressed therein lby an ordinary hand pump (not shown) gf'through this hollow port 96,.'- fllo explode s'-'rearof the piston 21 when it is explodedl this initial charge as Well as the regular charges I have provided theengine with the aforesaidv ordinary spark plug 92 and this spark pfug may be connected up with a source of electric energy shown as a storage 7.0 battery 197 by means of a Wire 104, there being a metallic ring, 98 secured lixedly to the main drive shaft 16 and insulated therefrom by a fibrous ring 99, the metallic ring having contacts 100 and 101 adapted to ro- 75 tate into engagement with the Contact 102 secured to and insulated from the bracket arm G9 with which a wire 103 connects it with one pole of the spark plug 92. One pole ofthe battery is connected by a Wire 80 104 to the spark plug 92 with a Wire 105 leading to the wire 106 to which is electrically connected a brush 107 engaging at all times the aforesaid annular ring 99. When' the contacts 100 and 101 separately contact 85 'with the single contact 102 a spark is made' from the spark plug 92 through said battery wires and brush behind the corresponding piston 20-21, there being as many contacts on the ring 99 as there are pistons car- 90 ried by the piston carrier with a switch 108 in the wire 10a to make and break the circuit when desired. Any other electrical connections for the spark plug may be employed. l 95 In order to properly cool the various parts of the engine have provided the same with a water acket 109 in which there is an opening 110 through which Water may be supplied and caused to circulate up over the 100 top of the engine with an outlet 111 for drawing over any Water that may remain at the top of the engine when it is desired to remove water from the jacket 109. This jacket or chamber 109 in the abutment ex- 105 16 and provide branch pipes 113 which comll municate With the duct 112 for conveying Water into thegcharnbers 114 of the piston carrier. At the"outer end of the shaft the duct 112may be closed as is obvious. As a matter of fact, `the Water in the chambers would be confined .therein incident to centrifugal force. By this arrangement Iam able to keep the rotary? piston .carrier and the compression chambers cool.

To prevent burning of oils and gases and consequentl smoking and undue heating of the engine by burning oils, and gases, I preferably dispose in each port 27 5 leading from the combustion chamber toA the lubricant lchambers 25 aspring controlled ball valve 130 y :theme29 with a ball 115 held normally against the shoulders 116 adjacent the inner' ends of the ports by the springs 11.7 supported by the ported plufs or bushings 118. These spring controlled Ellall valves prevent the ases from passing into the chambers 25 an( they seal the latter against loss of lubricant back into the explosion chamber so that there is alj Ways confined in the chambers 25 and also in the ports 27 a full supply of lubricant. In other Words,

are maintained closed because of the rotateble piston carrier 18 operating against the Wall of the. explosion chamber directly over the same as has been stated. By' this method of supplying the lubricant and maintaining the chambers 25 and the ports 27 full of the lubricant, the lubrication necessary is practically inexpensive.

From the foregoing it will be understood that pistons 2O and 21 are counterbalanced one by the other and that the plungers 58 and 59 are also counterbalanced one by the other. The plungers are guided and supported by compensating rings of the same form and construction as the compensating rings by Which the pistons are guided and supported and by virtue of the compensating rings of both the plungers and the pistons being operatively connected together and mounted on the same centers, there is coperation between` the plungers and theV pistons and an even and positive operation of one plunger with relation to the other and of one piston with relation to the other with the compensating rings of thc plungers having oscillatory movement on each other and the piston compensating rings having oscillatory movement one on the other. It Will also be seen that by means of a single valve consisting of a fixed and a movable element l am enabled to control the admiXture of the {iuids and the compression thereof and transfer of the 'same to the explosion chamber to operate the engine.
